I want to read X and Y axis from a text file, store them in a matrix, and then use "fprintf" to save the results.

I do not want to use "identifier" in the code.

This is the text:

# version
# sdim
# number of points
# lowest mesh point index
point coordinates

0.30000000000000004

I appreciate any suggestion.

Thank you in advance.

I use the following code. I want to modify the code without using "identifier".

 function [PointMatrix] = m ( ~ )
 i = 1; 
 identifier = {' point coordinates'};
 addpath('C:\Users \Desktop');
 fid = fopen(strcat(point '. txt'));
 while ~feof(fid)
    readLine = cellstr(fgets(fid));
    if strcmp(readLine, identifier(1))
        while(~strcmp(readLine, cellstr('')))
            readLine = cellstr(fgets(fid));
            Point(i, :) = readLine;
            i = i+1;
        end
        Point(end, :) = [];
        for i = 1:size(meshPoint, 1)
            PointMatrix(i, :) = str2num(cell2mat(Point(i)));
        end
        clear 'Point';
        i = 1;
        end
